I use DXwatch as my primary dx cluster for years now. Funny how it never crossed my mind I could also make an account for this site so I also can add spots.
The other day I signed up for an account (free) and I discovered another cool thing! You can create filters for specific spots and when that spot appears on DXwatch, DXwatch will send you a mail and/or an IM!

Pretty cool! I should sign up way earlier! 😉
